The Utah legislature has reinstated the Dependent with a Disability Exemption. This means you can claim an additional exemption on your Utah income taxes for dependents who have certain qualifying disabilities. This can help lower the amount of Utah income taxes you owe. The link below gives a full explanation, including the categories for eligibility. The main thing you should remember, however, is that you are required to complete a form TC-40D (link below) for each dependent that qualifies. The form requires that you get a signature from your school district or other agency, so don't wait till the last minute!
